Materials
A durable door needs to be manufactured from the materials of proper strength. This is obvious. That is why the sections of the KRISPOL garage doors are made of fire-galvanised, polyester-coated steel plates.
Their walls thickness is 0.5 or 0.7 mm. The section is filled with the layer of non-freon polyurethane foam ensuring good thermal and acoustic insulation.
The thermal insulation indicator ranges between 1.1 – 1.5 W/m2K and is dependant on, among others, panel or glazing type.
